Re: BUMP
Not sure if this is appropriate. but I had to respond to Faith's summation post on the "We have the fossils ..." thread.

Basically, she says that she wishes only to discuss real strata that are extensive and 'flat-lying', and are the basis for the geological column. She produces two images from disparate locations not in the Grand Canyon which are examples of such strata.

Well, I wonder if she will explain the sand channel that is highly visible in the Buffalo Sandstone in the first image. It clearly pinches out almost completely to the right side of the roadcut.

In the second image, I'd like to know the formation involved because it looks like a lacustrine deposit; and lakes are usually limited in extent and form in, ... well ... low places in the topography, er ... landscape.

Re: BUMP
Basically, Faith is as willfully ignorant about what a geological column is as she is about what the Bible says.

Since she has decided to not understand what a geological column is or what reality is or what geology actually shows all she can do is regurgitate the dogma of her Cult.

Can one person be a cult?

Flagged "off-topic"
Not that it wasn't off-topic at the "Fossils" topic, but I'm going to try to squelch it here.

But I think a somewhat more expanded version of your message (with graphics) might make for a good new topic. Please propose away.

Or something like that.

...perhaps a quick treatment...

quote:
Perhaps Edge would be up to the task of re-outlining the difference between the textbook version of the geologic column,...

Actually, I have a text in front of me that shows 15 different geological columns for the Cambrian alone... I think what you mean here is the 'geological column as most YECs see it'. This is actually the Geological Time Scale as your first site points out quite well. There is basically one time scale. How it got filled with rocks is a different story. Every location on earth has its own geological column.

quote:
... and the real world version of the geologic column.

Yes, this (these) are the real story. They represent the actual rocks occurring at a given location, in order of occurrence. They essentially fill in the time scale 'trays' with rocks. In most cases, not all periods of the time scale are represented. This is not unexpected or a violation of some geological precept.

In fact, we expect gaps, some of them quite large. This is because of erosion or non-deposition of rocks in those gaps which we generalize as 'unconformities'. We know unconformities are real, because we live on one. There have been no significant sedimentary rocks deposited on the Canadian shield (for instance) for as long as anyone can remember.

quote:
I know we've had some discussion of this in the past. In short, the textbook version is a timeline, which really says nothing about rocks. This is why there is a lot of truth to the statement "The geologic column only exists in textbooks".

IF one equates the geological column with geological time scale, yes. However, that is only done by YECs as far as I know.

There are as many geologic columns (stratagraphic columns) as there are points on the Earth. Such are essentially one specific locations fragment of a larger geologic cross section.

Now there are such things as generalized geologic columns, where the characteristics of a larger geologic cross section or even an area are condensed down to a "cartoon" column. Such illustrate relationships of the areas geology but should not be literally interpreted as being truly real.

When geologists are talking about a geologic column, one must consider the context of the discussion. They might be talking about the stratigraphy of a specific location. BUT if it is a broad discussion of THE GEOLOGIC COLUMN, geologic column is (probably) being used as an alternative phrasing for THE GEOLOGIC TIME SCALE.

Here in northern Minnesota, a group of geologists may talk of going out and looking at the preCambrian. That does not mean they are planning on doing some time travel. It means that they are going to be looking at some rocks of preCambrian age.

Re: Well...
Since you haven't had the opportunity to complain about me in some time I thought I'd be kind and offer you one.

I don't really get the big deal about this topic. So the geological column is different all over the world, so what? it's still a series of rocks wherever it is found that represents the geological time scale and in fact is the basis for it.

However it does make me curious to know what the differences are, how different the rocks are in different locations, how different the fossils, if anybody would like to sketch that out.
